This invention relates to footwear gpound} ing or burnishing machines, and more parend plates. 7 mounted onfreely extending pins' so that "h'eadyaccording to the invention".

Fig. '3 is a side elevation thereof; half ticularly to the poundingheads or drums of such machines, in w hic'h a' number of pounding elements are loosely and turna' bly mounted upon rods extending between two ends plates.

The main objectofthe 'inventionis to 'provide a poundingdrum with which it will be possible to pound or burnish boots and shoes at such places where thelritherto usual means failed to .reach the leath'er as, for

example, the cavities of strongly arched footwearand similar places.

A further ob 'ect'is the general improved constructionand arrangement of the 'drum and its pounding elements as will be fully set forth. p I

With these and other -:obj'ects in, view the invention mainly consists in providing the drum, in addition to its "usual arrangement of elements between'thetwo'end plates, with further pounding elements'outside the said These external elements are they'are'able 'better to reach into any-cavities such as a lasted shoe:.or-bo ot may present,

In the accompanying drawings several struction.

For the sake of-clearnessallfront'views are shown with the top and bottom-dines of poundingelements only.v i I First ofa ll the mode of operation of the known devices may be'explained; reference being had to Fig. 1 of'the drawings. In this figure, 1 is the working shaft to which the end plates or carriers 2, 2 are rigidly connected. These end plates carry a number of rods 3 between them, which are spaced all around the circumference at a short distance therefrom. The said rods 3 carry the pounding element which, in all the examples shown, consist of rollers 4. When working on 'ar'shoe or boot having a strongly .ex-., pressed arch such as indicated at w in Figs. land 2, it is evident that'therollers '4 will not be able to reach all partsof the cavity. As a matter of fact,it' is usually only the ball portion ofthe shoe with which the rollers are able to contact, as "indicated at 4, (Fig. 1) whilst the'heel portion can not he reached by the rollers owing to its' interfering with the end plates as at 2" (Fig. 1).

The rollers 4 of Fig. 1 are therefore unable to contact and work upon theniateri'al at that place. Now, in order somewhat toalleviate this disadvantage ithas been proposed 'tomountthe rods as close as possible tothe circumference of the endplatesfl andJ'Q to cause 'the rollers to project further beyond end plates." However, in 'view of the considerable centrifugal forces set up "by the high rotary speed ofthe drum, thelrods cannot be placed so near the":circumference as to remove the said drawback. y

*In the arrangement according to the invention as shown in Fig.12, the rollers '4"are arranged upon the rods 3 not only between the two end plates 2 and 2 as in the above example, but also sees to extend from their outer faces as shown at 4. "Like the rollers 4}between saidjplates'ythe r6llersf4 maybe concentric or *eX'centric', or in t'heshape both simple and e'lfectiv e'a. As will ibezapparent from Fig; 2 tl1eele1nents 4-outside the end plates can be' brought to ibear upon leven the'adeepest places of the cavityzwitlr out their action beingin ithe 'l east iinterfcred ixItis advisable to provide fixing means for w the axially protruding rollers 4, such'sa's pin heads 6 ;-for 'e-xample, in such manner a's' to preclude their hindering the action of the rollers in any way. For this reason "the heads of the fixing screwsLor-gpihs 6 may be made comparativelyflat, or they may be countersunk into the last ring or roller of. each line. It is also advisable to round off the edges of the outermost rollers as indicated at 7, in order to prevent the leather of the boots or shoes under treatment becoming scratched or otherwise damaged. Besides, the rollers, when rounded off in this way, will snugly fit the shanks of the shoes and thus be most effective 'intheir action.

end plates 2 and 2. Said rods 3 are secured against turning by platesectors 8 which project into slots or recesses 9 cut therein, whereas the sectors themselves are retained upon the end plates 2, 2 by means of screws 10 passing through slots 11 in the said sector v tion a rotary member, pins ext-ended freely plates, so as to be adjustable.

1 Fig.4 shows a modified arrangement of the pounding" elements in that the rollers 4 are positioned upon rods 12 extending between the end plates 2, 2* in the usual inanner, while the external rollers/l are mounted on short studs or pins 13 externally fixed in said end plates in alternating succession with the said rods 12. According to the sense of rotation it is advisable to use right hand threaded screws or bolts at one side of the dr m, and left hand threaded screws or bolts at the other side. In thisway no special locking means need be employed.

The same advantageous results as mentioned above can be obtained with the con- .struction shown in Fig. 5. In this case, however,.only one carrier plate 14. is provided instead of the two end plates 2 and 2. and the elements 1 are arranged on pins .15 passing through the said plate so as to project therefrom at both sides.

It will be readily understood that in addition to the usual way of applying the work to the front of the drum, the invention admits of the workpiece being moved cornerways around the edges of the drum where it will. also be hit by pounding elements without the risk of contacting with portions of the body or frame ofthe drum. Thus any grinding, tearing or otherwise undesirable effects upon the workpiece are effectually avoided.

What I claim is 1 1. In a pounding drum for footwear pounding machines, a rotary carrier having looselyarrange'd pounding. elements extendingfreely from the outer facesof-said drum.

on opposite sides thereof.

2. In a; pounding dr'um 'for. footwear pounding machines, the provision of pounding elements mounted to extend freely beyond the outer faces of the drum. 3. In a pounding. drum for footwear pounding machines embodying end-plates and pounding elements, the provision of pounding elements at the outside of the end 'tion a rotary member, pins extendingfrom the outer faces of the said member in axial direction, and pounding elements mounted upon the said p1ns.-*

5. A pounding drum having in combinafrom the outer faces of the said member in axial direction,-pounding element s mounted upon the said pins, and rounded holding means at the ends of the said pins.

6. A pounding drum comprising two end plates, rods extending between the said end plates circumferentially thereof, pounding elements loosely and turnably mounted upon the said rods, pins extending from the outer faces of the said end plates, further pounding elements mounted upon these pins, and rounded heads to the said pins to retain the pounding elements inposition. v

7. In a pounding drum for footwear pounding machines. the arrangement of pounding elements upon rods arranged circumferentially between revoluble carrying plates, and of pounding elements similarly arranged on flying pins at the outer faces of the said carrying plates, .said rods and the said flying pins being arranged in alternating succession around the circumferenceof the carrying plates.

8. A poundingdrum having in combination a rotary member, pins freely extending from the outer faces of the said member in axial direction, pounding elements mounted on the said pins, slots in the pins adjacent the outer faces of the rotary member, and ring segments to engage the saidv slots and thus lock the said pins in position.
